Collapsible chorus stand



Aug. 11, 1931. M. PA-YSEN COLLAPSIBLE CHORUS STAND I Filed Aug. 2. 1930Patented Aug. 11, 1931 MAGNUS IPAYSEN, OF HEBRON, NEBRASKA COLLAPSIBLECHORUS STAND Application filed August 2, 1930. 7 Serial No. 472,621.

My invention relates to chorus stands and more particularly to chorusstands of the collapsible type in which the stand may be folded into asize and form so that it may be easily carried about and in which itwill occupy the minimum of storage space when not in use. 7

The primary object of the invention is the provision of a foldable orcollapsible chorus stand which is firm and rugged when in use but whichmay be folded so that it may be easily carried about from place toplace.

Another of my objects is the provision of a plurality of shelves orplatforms having supports to which the platforms are hingedly connectedand with inge connections between the supports. 7

Another of my objects is the provision of a reinforcing and latchingmember which will strengthen the structure while in use and which willrender the hinge connections inoperative during use to thereby preventthe accidental collapsing of the chorus stand.

Having in view these objects and others which will be pointed out in thefollowing description, I will now refer to the drawings, in which Figure1 is a view in perspective of the chorus stand fully set up for use.

Figure 2 is a view in end elevation of the chorus stand showing theposition of the reinforcing and latching member and showing also thehinge which connects the two supports.

Figure 3 is a view similar to Figure 1 but showing the various parts intheir position at the beginning of the collapsing movement.

Figure 4 is an end elevation of the partially collapsed chorus stand.

Figure 5 is a view in perspective showing the chorus stand completelycollapsed.

The chorus stand includes a pair of platforms and 11 having supports 12and 13 respectively, the platforms being connected to the supports bymeans of hinges 1 1 and respectively. The supports in each instance areconnected with each other by means of hinges 16, these hinges being onthe side of the supports opposite the hinges 14 and 15.

The stand may be made of any suitable might be desirable.

supports 12 and 13 are provided but these alone mightbe insufficient tomaintain the material such as wood or steel. The platforms 10 and 11' inmy present models are made from planks of suitable length and widthwhich are secured to the supports 12 and 13 of similar material.

As thus far described the collapsing movement of the various parts willbe readily understood. The pintles of the hinges 14 and 15 are alltransverse and parallel to each other. Parallel movement of theplatforms l0 and 11 relative to each other will take place about thepintles of the hinges 14 and 15 until the two platforms 10 and 11 lie ina common plane. The initial step of this move- 7 ment is shown in Figure3 in which all of the supports 12 and 13 are inclined with reference tothe two platforms 10 and 11. WVhen the platforms 10 and 11 are ina'common plane, the supports 12 and 13 all lie within a. plane common toall of the supports, this plane being parallel to the plane of theplatforms 10 and 11. At this point the pintles of all of the hinges 16will be brought into alignment so that it is'possible to fold the twoplatforms 10 and 11 into parallel planes with the supports 12 and 13between the two platforms. As thus far described the chorus stand mightbe'accidentally collapsed during use and the stand itself would not beas firm as A suitable number of two platforms 10 and 11in firm conditionwhen they carry a heavy weight. In order to reinforce the structure,there is provided a beam 17 which is hingedly connected at 18 to therear. edge of the platform 11. The

hinges 1 8 are so secured to the platform 11,

and to the beam 17 that the beam 17 is alwith'the rear edges of thesupports 13 when the chorus stand is set up and ready for use. The pairsof cleats 19engage the rear edges of the supports 13 and thereby holdthesupports 12 and 13 against any movement on the hinges 1 1 and 15. Nocollapsing movement of the stand can take place without first releasingthe supports 13 from engagement with the cleats 19.

The platforms 10 and 11 may be made in any desired dimensions. It isalso obvious that the stand need not be limited to two platforms asshown in my drawings but any number of platforms may be provided bybuilding up the structure as indicated and by hinging the beam 17 withits latches 19 to the rearmost or uppermost platform. The only limit tothe number of platforms is the limit necessitated by the increasedweight and by the increased bulk of the folded stand.

The stand is designed initially and primarily to serve as a chorusstand. The dimensions of the parts may, however, be altered at will sothat the stand will serve as a support for goods which are to bedisplayed in a store or in a store window. I therefore reserve to myselfthe right to all uses to which the stand may be put.

Having thus described my invention in such full, vclear, and exact termsthat its construction and operation will be readily understood by othersskilled in the art to which it pertains, what I claim as new and desireto secure by Letters Patent of the United States 1S 1 1. A chorus standcomprising a pair of platforms each having a. support hin edly securedthereto, said supports being folc able into parallelism with saidplatforms, each pair of said supports being in edge to edge relation andin a. common plane when said chorus stand is set up, and hingeconnections between the members of a pair of said supports whereby themembers of the pair of supports are foldable on each other in parale lelplanes. I

2. A chorus standcomprising a pair of platforms at different levels eachhaving a support hingedly secured thereto, said supports being foldableinto parallelism with said platforms, each of said supports being inedge to edge relation andin'a common plane when said chorus stand is setup, and hinge connections between the supports of a pair of saidsupports whereby the members of a pair of supports are foldable on eachother into parallel planes and whereby the folding of said supports onsaid platforms results in a parallel movement of said platforms to bringthem into a common plane and in edge to edge relation. 7

3. A chorus stand comprising a pair of platforms each having a supporthlngedly secured thereto, said supports being foldable into parallelismwith said platforms, each pair of said supports being in edge to edgerelation and in a commonplane when said v chorus stand 1s set up, hmgeconnections between the supports of a pair of said supports whereby themembers of a pair of supports are foldable on each other into parallelplanes, and a latch for releasably uniting one of said platforms to thesupport thereof to prevent relative movement therebetween when saidchorus stand is set up.

4:. A chorus stand including an upper platform, a plurality of supportstherefor, hinges connecting said supports to said upper platform, theaxes of said hinges positioned transversely of said upper platform, alower platform immediately forward of said upper platform, supports forsaid lower platform hingedly secured thereto with the hinge axespositioned transversely thereof, hinges having vertical axes connectingthe supports of said lower platform to the supports of said upperplatform whereby said chorus stand is foldable about the hinges havingtrans- Verse axes to bring said two platforms into a common plane and inedge to edge relation and with the axes of said support-connectinghinges in alignment whereby saidtwo platforms are foldable into paralleland spacedapart relation with said supports positioned in foldedrelation between said platforms.

In testimony whereof I afiix my signature.
